The size-dependent elastic property of rectangular nanobeams （nanowires or nanoplates） induced by the surface elas- ticity effect is investigated by using a developed modified core-shell model. The effect of surface elasticity on the elastic modulus of nanobeams can be characterized by two surface related parameters, i.e., inhomogeneous degree constant and surface layer thickness. The analytical results show that the elastic modulus of the rectangular nanobeam exhibits a distinct size effect when its characteristic size reduces below 1 O0 nm. It is also found that the theoretical results calculated by a mod- ified core-shell model have more obvious advantages than those by other models （core-shell model and core-surface model） by comparing them with relevant experimental measurements and computational results, especially when the dimensions of nanostructures reduce to a few tens of nanometers.

Based on the reverse microemulsion technique, luminescent quantum dots doped core-shell nanoparticles have been prepared by employing silica as the shell and CdTe quantum dots as the core of the nanoparticles, which have an excellent solubility and dispersibility, especially amine and phosphonate groups have been modified on their surface synchronously. In comparison with CdTe quantum dots, these nanoparticles show superiority in chemical and photo-chemical stability. The quantum dots doped core-shell nanoparticles were successfully linked with lactobionic acid by amine group on it, which was used to recognize living liver cells.

Young male albino rats were fed ad libitum semipurined diet supplemented with or without 5% of purified dietary fiber (cellulose, agar-agar, pectin, chitin or chitosan) for 31 days. Each test diet was carefully prepared in order to contain zinc at the level of 8 ppm from zinc *** rats fed diets containing 5% of dietary fiber except chitosan, fbod consumption was higher than the control. The body weight gain of rats fed diets containing cellulose, pectin or chitin was higher than the control. However, food intake and body weight gain of rats fed the diet containing 5% of chitosan were definitely lower than not only the other fiber including diet groups but also the control *** dietary fiber was added at 5% level to diet, zinc absorption was not changed to a considerable degree. But, the apparent zinc absorption of rats fed the agar-agar diet was 70%. On the other hand, zinc absorption in the pectin diet group was about 10% higher than the *** total amount of zinc in tibia or femur of rats fed non-fiber diets was a little higher than that of rats fed fiber diets

AIM: To study the effects of aminoguanidine (AG) and two L-arginine analogues N(omega)-nitro-L-arginine methyl ester (L-NAME) and N(omega)-nitro-L-arginine (L-NNA) on nitric oxide (NO) production induced by cytokines (TNF-alpha, IL-1 beta, and IFN-gamma) and bacterial lipopolysaccharide (LPS) mixture (CM) in the cultured rat hepatocytes, and examine their mechanisms action. METHODS: Rat hepatocytes were incubated with AG, L-NAME, L-NNA, Actinomycin D (ActD) and dexamethasone in a medium containing CM (LPS plus TNF-alpha, IL-1 beta, and IFN-gamma) for 24h. NO production in the cultured supernatant was measured with the Griess reaction. Intracellular cGMP level was detected with radioimmunoassy. RESULTS: NO production was markedly blocked by AG and L-NAME in a dose-dependent manner under inflammatory stimuli condition triggered by CM in vitro. The rate of the maximum inhibitory effects of L-NAME (38.9%) was less potent than that obtained with AG(53.7%, P < 0.05). There was no significant difference between the inhibitory effects of AG and two L-arginine analogues on intracellular cGMP accumulation in rat cultured hepatocytes. Non-specific NOS expression inhibitor dexamethasone (DEX)and iNOS mRNA transcriptional inhibitor ActD also significantly inhibited CM-induced NO production. AG(0.1 mmol x L(-1)) and ActD (0.2 ng x L(-1)) were equipotent in decreasing NO production induced by inflammatory stimuli in vitro, and both effects were more potent than that induced by non-selectivity NOS activity inhibitor L-NAME (0.1 mmol x L(-1)) under similar stimuli conditions (P<0.01). CONCLUSION: AG is a potent selective inhibitor of inducible isoform of NOS,and the mechanism of action may be not only competitive inhibition in the substrate level, but also the gene expression level in rat hepatocytes.

LiVO was synthesized using theological phase reaction method. First, the mixture of LiAc·2H2O,NH3VO3,citric acid and a required amount of water reacted to form the theological precursor. The product LiV3O8 was obtained by sintering the precursor at 400℃for 10h. TG was employed to analyze the precursor. The LiV3O8 product which was characterized by XRD and SEM indicated that LiV3O8 has been obtained by this novel synthesis method. The electrochemical performance has been investigated. As a result, the LiV3O8 obtained at 400℃for 10h has excellent electrochemical properties, the first discharge of which was 272.9mAh/g in the rang of 1.8-4.0V at 0.3mA·cm-2. The novel method provides an inexpensive, simple and effective route for inorganic material synthesis.
